It is suitable for use in crowd simulations (e.g. indoor evacuation simulation, large scale outdoor simulations), where quantitative measurements like pedestrian density or evacuation time matter. The quality of the individual agent's trajectory is high enough for creating massive pedestrian crowd animations (e.g. for motion pictures or architectural visualization). Since PEDSIM is easy to use and extend, it is a good starting point for science projects. 3 | 4 | # License 5 | This software is free software: 6 | You can redistribute it and/or modify it under the terms of the GNU General Public License (GPL).

It listens on 7 | a network socket for update information (agent positions, but also 8 | dynamic scene definitions.), which are rendered in real-time. This is 9 | perfectly suited to observe stand-allone simulations or optimizations 10 | which take a long time to run. Also nice for demonstrations, where the 11 | visualizer is installed on the machine connected to the beamer, and 12 | the simulation runs on a separate host. Ah and yes, it is able to 13 | output png files for each frame, which can be combined into a video 14 | easily! 15 | 16 | _2dvis_ is built on _Qt_. If you want to use all the features (especially 17 | charts), you need _Qt 5.7_ or above. It should be possible to compile it 18 | using an older version. However, you will not see the metrics charts in 19 | _2dvis_ then. See documenation for compiling on [Linux](@ref linux) and 20 | [Windows](@ref windows). 21 | 22 | 23 | ## Usage 24 | 25 | ~~~~ .sh 26 | Usage: ./2dvis [options] 27 | 2-dimensional PEDSIM visualizer. 28 | 29 | Options: 30 | -h, --help Displays this help. 31 | -q, --quiet Do not show graphical output 32 | -n, --network Read input from network on port 33 | -f, --file Read input from 34 | -c, --charts Display charts DockWidget 35 | -m, --metrics Display metrics DockWidget 36 | -o, --outputdirectory Write frame-by-frame image output to 37 | ~~~~ 38 | 39 | Usually, `2dvis` is started in network mode, where it listens to 40 | incoming data packets on the specified UDP port. 41 | 42 | ~~~~ .sh 43 | ./2dvis -n 2222 44 | ~~~~ 45 | 46 | ## Metrics and charts display 47 | 48 | 2dvis has the ability to display user-defined metrics coming from the 49 | simulation. It can display the latest metrics in numerical form, and 50 | also chart the values as line graphs. These two dockable windows are 51 | enabled by specifying `-m`/`--metrics` or `-c`/`--charts` respectively 52 | on the command line. Note that the charts window needs _Qt_ version 53 | 5.7 or above. Otherwise the feature will not be compiled in. Numerical 54 | metrics work for all _Qt_ versions. 55 | 56 | These metrics are submitted from the simulation using 57 | Ped::XMLOutputWriter::writeMetrics(std::unordered_map hash). For example like this: 59 | 60 | ~~~~ .cpp 61 | ow->writeMetrics({{"name1", "value1"}, {"name2", "value2"}}); 62 | ~~~~ 63 | 64 | Here is an example with metrics transmitted: 65 | 66 | ~~~~ .cpp 67 | ow->writeMetrics({ 68 | {"Average Timesteps", std::to_string(sum_age/agents.size())}, 69 | {"Average Theta", std::to_string(sum_theta/agents.size())}, 70 | {"Average Sensitivity L", std::to_string(sum_sensitivity_l/agents.size())}, 71 | {"Average Sensitivity R", std::to_string(sum_sensitivity_r/agents.size())}, 72 | {"Average Reach", std::to_string(sum_reach/agents.size())} 73 | }); 74 | ~~~~ 75 | 76 | ![2dvis is a 2-dimensional visualizer for PEDSIM](2dvis_metrics.png) 77 | @latexonly 78 | \includegraphics[width=\textwidth]{2dvis_metrics.png} 79 | @endlatexonly 80 | 81 | ## Video generation 82 | 83 | Instead of a network stream it is also possible to process a XML file 84 | containing the messages. This is meant for creating videos. At the 85 | moment, 2dvis will try to play all events in full speed, resulting in 86 | an overloaded graphics engine.

It listens on 7 | a network socket for update information (agent positions, but also 8 | dynamic scene definitions.), which are rendered in real-time. This is 9 | perfectly suited to observe stand-allone simulations or optimizations 10 | which take a long time to run. Also nice for demonstrations, where the 11 | visualizer is installed on the machine connected to the beamer, and 12 | the simulation runs on a separate host. 13 | 14 | The difference between the two visualizers is that [2dvis](@ref 15 | twodvis) is intended for displaying a technical view of the scenario, 16 | while 3dvis show a "real" view. 3dvis does not render the scenario 17 | realistically in any way - however, it only shows what would be 18 | visible in real live - i.e. no waypoints or forces. 19 | 20 | _3dvis_ is built on _Qt_. You need _Qt 5.7_ or above with Qt3D (might 21 | be included, check when you install Qt). See further documenation for 22 | compiling on [Linux](@ref linux) and [Windows](@ref windows). 23 | 24 | 25 | ## Usage 26 | 27 | `3dvis` is always started in network mode, where it listens to 28 | incoming data packets on the specified UDP port. In contrast to 2dvis, 29 | it can not render file based input. 30 | 31 | ~~~~ .sh 32 | ./3dvis 33 | ~~~~ 34 | 35 | ## Video generation 36 | 37 | There is no built in video generation mode for 3dvis. In order to 38 | caputre a video from a 3dvis animation, use a 3rd party capture tool, 39 | ideally one that supports your 3D graphics card natively. 40 | 41 | ## Supported XML tags 42 | 43 | See [here](@ref xml) for a list of valid XML tags. However, 3dvis does 44 | not render all tags. It only renders objects that have a physical 45 | representation, e.g. agents or obstacles. 46 | 47 | ![3dvis is a 3-dimensional visualizer for PEDSIM](3dvis.png) 48 | 49 | @latexonly 50 | \includegraphics[width=\textwidth]{3dvis.png} 51 | @endlatexonly 52 | -------------------------------------------------------------------------------- /ecosystem/3dvis/documentation/3dvis.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/chgloor/pedsim/0d8ff5c652ee2a1a59cea68a638d7ef399f41048/ecosystem/3dvis/documentation/3dvis.png -------------------------------------------------------------------------------- /ecosystem/3dvis/item.cpp: -------------------------------------------------------------------------------- 1 | // 2 | // pedsim - A microscopic pedestrian simulation system. 3 | // Copyright (c) by Christian Gloor 4 | // 5 | 6 | #include "item.h" 7 | 8 | #include 9 | #include 10 | #include 11 | #include 12 | #include 13 | 14 | Item::Item(Qt3DCore::QEntity *rootEntity) : Qt3DCore::QEntity(rootEntity), transform(new Qt3DCore::QTransform), r(0) { 15 | // does basically nothing for the time being. 16 | } 17 | 18 | void Item::updateComponents() { 19 | transform->setTranslation(QVector3D(x, z, y)); 20 | //transform->setRotation(QQuaternion::fromAxisAndAngle(QVector3D(0, 1, 0), r)); 21 | }; 22 | 23 | -------------------------------------------------------------------------------- /ecosystem/3dvis/item.h: -------------------------------------------------------------------------------- 1 | // 2 | // pedsim - A microscopic pedestrian simulation system. 3 | // Copyright (c) by Christian Gloor 4 | // 5 | 6 | #ifndef ITEM_H 7 | #define ITEM_H 8 | 9 | #include 10 | #include 11 | 12 | class Item : public Qt3DCore::QEntity { 13 | public: 14 | Item(Qt3DCore::QEntity *rootEntity); 15 | virtual void updateComponents(); 16 | 17 | double x; 18 | double y; 19 | double z; 20 | double r; // rotation 21 | 22 | 23 | protected: 24 | Qt3DCore::QTransform *transform; 25 | 26 | }; 27 | 28 | #endif 29 | -------------------------------------------------------------------------------- /ecosystem/3dvis/itemagent.cpp: -------------------------------------------------------------------------------- 1 | // 2 | // pedsim - A microscopic pedestrian simulation system. 3 | // Copyright (c) by Christian Gloor 4 | // 5 | 6 | #include "itemagent.h" 7 | 8 | #include 9 | #include 10 | #include 11 | #include 12 | #include 13 | 14 | 15 | ItemAgent::ItemAgent(Qt3DCore::QEntity *rootEntity) : Item(rootEntity) { 16 | Qt3DExtras::QGoochMaterial *material = new Qt3DExtras::QGoochMaterial(rootEntity); 17 | 18 | Qt3DCore::QEntity *entity = new Qt3DCore::QEntity(rootEntity); 19 | material->setDiffuse(QColor(QRgb(0xaaaaaa))); 20 | 21 | Qt3DExtras::QCylinderMesh *m = new Qt3DExtras::QCylinderMesh; 22 | m->setRadius(0.75); 23 | m->setLength(2); 24 | m->setRings(30); 25 | m->setSlices(10); 26 | 27 | entity->addComponent(m); 28 | entity->addComponent(transform); 29 | entity->addComponent(material); 30 | } 31 | 32 | void ItemAgent::updateComponents() { 33 | transform->setTranslation(QVector3D(x, 1.0+z, y)); 34 | //transform->setRotation(QQuaternion::fromAxisAndAngle(QVector3D(0, 1, 0), r)); 35 | }; 36 | -------------------------------------------------------------------------------- /ecosystem/3dvis/itemagent.h: -------------------------------------------------------------------------------- 1 | // 2 | // pedsim - A microscopic pedestrian simulation system. 3 | // Copyright (c) by Christian Gloor 4 | // 5 | 6 | #ifndef ITEMAGENT_H 7 | #define ITEMAGENT_H 8 | 9 | #include 10 | #include 11 | 12 | #include "item.h" 13 | 14 | //class Item : public QGraphicsItem { 15 | class ItemAgent : public Item { 16 | public: 17 | ItemAgent(Qt3DCore::QEntity *rootEntity); 18 | virtual void updateComponents(); 19 | 20 | 21 | }; 22 | 23 | #endif 24 | -------------------------------------------------------------------------------- /ecosystem/3dvis/itemcontainer.cpp: -------------------------------------------------------------------------------- 1 | // 2 | // pedsim - A microscopic pedestrian simulation system. 3 | // Copyright (c) by Christian Gloor 4 | // 5 | 6 | #include "itemcontainer.h" 7 | #include "item.h" 8 | 9 | #include 10 | 11 | extern Qt3DCore::QEntity *scene; 12 | 13 | 14 | ItemContainer::ItemContainer() {} 15 | 16 | // Removes all items from the container 17 | void ItemContainer::clear() { 18 | container.clear(); 19 | } 20 | 21 | void ItemContainer::for_each(void (*fn)(Item*)) { 22 | QHash::iterator it; 23 | for (it = container.begin(); it != container.end(); ++it) { 24 | fn(*it); 25 | } 26 | } 27 | 28 | void ItemContainer::removeItem(QString id) { 29 | // scene->removeItem(container[id]); 30 | container[id]->z = -100; // don't know how to remove from scene.

This was PEDSIM version 1.x. For version 2.x, PEDSIM has 9 | been separated into a library and the Demo Application. These two 10 | pieces of software do more or less the same as PEDSIM Version 1.x, but 11 | with less import/export and scenario analysis features. 12 | 13 | The main focus of development is on the PEDSIM library, since it is 14 | assumed that interested users are quickly able to develop their own 15 | software using the library. The Demo Application is still being 16 | maintained, but no longer extended. Its purpose is now to show how 17 | `libpedsim` can be used in a flexible way. It uses OOP inheritance to 18 | achive a tighter integration. These offers possibilities beyond what 19 | is presented in the code examples. 20 | 21 | At the same time the Demo App is used as a _manual_ integration test 22 | case. The library contains unit and user acceptance tests, based on 23 | the Google test framework. These tests are run automatically and are 24 | supposed to cover all possible aspects of failure. However, I believe 25 | that in the end a human has to look at the output of the system and 26 | judge if everything still looks sane. This is what the Demo 27 | Application is used for internally. 28 | 29 | The scenario input features mentioned above are still a good starting 30 | point for your own small experiments. It is possible to define a 31 | scenario by writing a simple XML file, and use the user interface to 32 | quickly play with the various forces of the underlying model. 33 | 34 | ## More Documentation 35 | 36 | - @ref demoapp_gui 37 | - @ref demoapp_scenario 38 | 39 | ## Compilation 40 | 41 | Qt is needed to compile and run the demo application! See the 42 | installation documentation on [Linux](@ref linux) and [Windows](@ref windows) 43 | for more information regarding compillation of the source 44 | code. 45 | 46 | Please note that (at least for the time being) the DemoApp does not 47 | link `libpedsim` dynamically using the .dll on Windows or the .so 48 | library on Linux respectively. This is due to bug related to 49 | incompatible compiler versions or settings in Qt and msvc15, which is 50 | often used to compile the library on Windows. 51 | 52 | The source of `libpedsim` is directly included in the DemoApp Qt 53 | project file. This means that there is no need to compile the library 54 | separately at the moment. Compiling the DemoApp will also compile and 55 | statically link the library into the code.

Display Options

13 | 14 |
    15 |

  • Show Waypoints - If this is checked, the waypoints are 16 | displayed. Only currently to an agent assigned waypoints can change 17 | their visibility, so you might have to wait a bit before all waypoints 18 | appear/disappear. Since several agents share one waypoint, it is not 19 | possible to display the details of the waypoint for each agent (they 20 | can adapt to the agent's direction). So only the information of the 21 | last agent assigned will be displayed, resulting in the waypoints 22 | changing their look during the simulation.

    23 |

  • Show Quadtree - Displays the quadtree used to store the 24 | agents internally. In order to find neighbors of agents quickly, they 25 | are grouped together in cells. These cells are generated and arranged 26 | dynamically.

    27 |

  • Show Direction - Displays the agent's direction. The yellow 28 | line represents where they actually do walk at the moment. The length 29 | of this line represents the velocity of the agent.

    30 |

  • Show Forces - Displays the forces that affect the individual 31 | agents. The forces are shown towards the direction the agents is 32 | accelerated. Red: direction they would like to walk to (desired 33 | direction). Blue: force that pulls them away from walls. Green: force 34 | that pulls them away from each other. Magenta: "Look Ahead" force.

    35 |

  • Framerate - Specify how many updates per second shoud be 36 | made. If the requested value is higher than what your computer can 37 | deliver, it will have no effect.

    38 |
39 | 40 |

Mental Layer Options

41 | 42 |
    43 |

  • Look Ahead - This mental layer strategy is a bit more 44 | sophisticated. Each agent looks ahead a certain distance and counts 45 | the other agents to his left, and to his right, respectively. It then 46 | walks slightly into the direction where less agents were counted. Only 47 | agents in front of the agent, and only those with a walking direction 48 | in the opposite direction are considdered. So walking in lines behind 49 | each other is not affected.

    50 |

  • Dijkstra Routing - Not implemented in this demo (yet?), because the scenario is too small for this feature.

    51 |

  • Visual Avoidance -Not implemented in this demo (yet?).

    52 |
53 | 54 |

Physical Layer Options

55 | 56 |
    57 |

  • Precision (h) - In each timestep (frame) of the simulation, 58 | the agent is allowed to walk forward a tiny step. All the 59 | accelerations and velocoties are scaled to match this step length. The 60 | precision defines how long such a step is (High precision = small 61 | steps). Setting precision too low will allow the angents to walk 62 | through walls and each other, since they only detect an obstacle when 63 | they are already through it. If the precision is high, the simulation 64 | will run very slowly, but the results are not supposed to change 65 | dramatically (except for rounding errors in the calculations, which 66 | can cause a slightly different overall result). The value h is also 67 | known as tau in literature and the documentation of the social force 68 | model.

    69 |

  • Wall Force - This slider defines how strong the force 70 | pushing away from the walls and other obstacles is (fiW). The higher 71 | it is, the bigger the distance an agent will keep from the wall will 72 | be. If the wall force is too low, agents will be able to walk through 73 | the walls. This will be more likely the larger the force between 74 | pedestrians becomes (see next slider), especially if the pedestrian 75 | density is very high (bottlenecks, or during an unevenly 76 | initialization).

    77 |

  • Pedestrian Force - Defines the distance each agent tries to 78 | keep from the other agents (fij). Set this to a high value if no 79 | mental layer strategies are activated (i.e. the simulation is run as a 80 | pure social force model simulation). Some mental layer strategies try 81 | to steer agents around other agents in advance, to this force is only 82 | used as a last change to avoid a collision. (or to actually simulate a 83 | collision, if set to a very low value.)

53 | 54 | -------------------------------------------------------------------------------- /ecosystem/demoapp/documentation/scenario.dox: -------------------------------------------------------------------------------- 1 | /** 2 | @page demoapp_scenario Scenario Definition 3 | 4 | 5 | # PedSim Demo App Documentation 6 | 7 | ## Scenario Definition 8 | 9 | The scenario of the simulation is defined in a simple XML file. The default is scene.xml, placed in the same directory as the executable. However, it can also be specified on the command line: 10 | 11 | ./pedsim myscenario.xml 12 | 13 |

There must be a top-level tag in each XML document. In the 14 | predefined scenario file scene.xml and in the examples, it is 15 | <scenario>. At this moment, it does not matter what you write in there - as long as you have exacly one top-level tag.

16 | 17 | ### Waypoints 18 | 19 |

The first item you should define are the waypoints, because they 20 | are used later in the agent definitions.

21 | 22 | A waypoint has coordinates x and y, and a 23 | raduis r. A waypoint definition also contains the 24 | waypoint id, which is used to reference it later: 25 | 26 | 27 | 28 | ### Agents 29 | 30 | Agent definitions are a bit more complex. An agent has a start 31 | position with coordinates x and y. 32 | 33 | Since it would not be comfortable to define each of potentially 34 | many agents individually, there is a way to specify groups of 35 | agents. In the agent definition, a agent multiplier n can be 36 | added. N copies of that agent will be spawned into the 37 | simulation. It would not be wise to place them all at the same 38 | location, so there is a way to spread them out a bit by specifying 39 | the dx and dy modifiers. The agents will be placed 40 | evenly distributed between x-dx and x+dx (resp y and 41 | dy). 42 | 43 | Each agent has waypoints assigned. It will walk from the initial 44 | position to the first waypoint, then to the second and so on. The 45 | waypoints are added inside the <agent></agent> 46 | tag. Each added waypoint is a reference to a waypoint defined 47 | earlier. Please make sure that only waypoints really specified earlier 48 | are referenced. 49 | 50 | #### Example 51 | 52 | 53 | 54 | 55 | 56 | 57 | 58 | ### Obstacles 59 | 60 |

Defining obstacles is very simple. Each obstacle is a line from 61 | coordinates x1/y1 to coordinates x2/y2. It is not 62 | relevant where they are added, or how they are grouped.

63 | 64 | 65 | 66 | ## Combined Example 67 | 68 | A box of four walls is defined, a waypoint on each side. 200 agents walk from one side of the box to the other. 69 | 70 | ~~~~~~~~~~~~~~~~ .xml 71 | 72 | 73 | 74 | 75 | 76 | 77 | 78 | 79 | 80 | 81 | 82 | 83 | 84 | 85 | 86 | 87 | 88 | 89 | 90 | 91 | 92 | 93 | 94 | 95 | 96 | 97 | ~~~~~~~~~~~~~~~~ 98 | 99 | 100 | This is a screenshot of the DemoApp displaying this example scenario: 101 | 102 | ![Pedsim Demo App](20120204-screenshot-v2-2.png) 103 | 104 | @latexonly 105 | \includegraphics[width=\textwidth]{20120204-screenshot-v2-2.png} 106 | @endlatexonly 107 | 108 | */ -------------------------------------------------------------------------------- /ecosystem/demoapp/documentation/screenshot.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/chgloor/pedsim/0d8ff5c652ee2a1a59cea68a638d7ef399f41048/ecosystem/demoapp/documentation/screenshot.png -------------------------------------------------------------------------------- /ecosystem/demoapp/pedsim.pro: -------------------------------------------------------------------------------- 1 | 2 | TEMPLATE = subdirs 3 | SUBDIRS = src 4 | 5 | 6 | #CONFIG += ordered 7 | 8 | CONFIG += release 9 | -------------------------------------------------------------------------------- /ecosystem/demoapp/pedsim.sln: -------------------------------------------------------------------------------- 1 | Microsoft Visual Studio Solution File, Format Version 12.00 2 | # Visual Studio 14 3 | VisualStudioVersion = 14.0.25420.1 4 | MinimumVisualStudioVersion = 10.0.40219.1 5 | Project("{8BC9CEB8-8B4A-11D0-8D11-00A0C91BC942}") = "pedsim", "src\pedsim.vcxproj", "{580BC3AE-FCDB-33EF-B903-94933DF5062D}" 6 | EndProject 7 | Global 8 | GlobalSection(SolutionConfigurationPlatforms) = preSolution 9 | Debug|x64 = Debug|x64 10 | Release|x64 = Release|x64 11 | EndGlobalSection 12 | GlobalSection(ProjectConfigurationPlatforms) = postSolution 13 | {580BC3AE-FCDB-33EF-B903-94933DF5062D}.Debug|x64.ActiveCfg = Debug|x64 14 | {580BC3AE-FCDB-33EF-B903-94933DF5062D}.Debug|x64.Build.0 = Debug|x64 15 | {580BC3AE-FCDB-33EF-B903-94933DF5062D}.Release|x64.ActiveCfg = Release|x64 16 | {580BC3AE-FCDB-33EF-B903-94933DF5062D}.Release|x64.Build.0 = Release|x64 17 | EndGlobalSection 18 | GlobalSection(SolutionProperties) = preSolution 19 | HideSolutionNode = FALSE 20 | EndGlobalSection 21 | GlobalSection(ExtensibilityGlobals) = postSolution 22 | Qt5Version = 5.7 23 | EndGlobalSection 24 | EndGlobal 25 | -------------------------------------------------------------------------------- /ecosystem/demoapp/scene.xml: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 28 | 29 | 30 | 31 | 32 | 33 | 34 | 35 | 36 | 37 | 38 | 39 | 40 | 41 | 42 | 43 | 44 | 45 | 46 | 47 | 48 | 49 | 50 | 51 | 52 | 53 | 54 | 55 | 56 | 57 | 58 | 59 | 60 | 61 | 62 | 63 | 64 | 65 | 66 | 67 | 68 | 69 | 70 | 71 | 72 | 73 | 74 | 75 | 76 | 77 | 78 | 79 | 80 | 81 | 82 | 83 | 84 | 85 | 86 | 87 | 88 | 89 | 90 | 91 | 92 | 93 | 94 | 95 | 96 | 97 | 98 | 99 | 100 | 101 | 102 | 103 | 104 | 105 | 106 | 107 | 108 | 109 | 110 | 111 | 112 | 113 | 114 | 115 | 116 | 117 | 118 | 119 | 120 | 121 | 122 | 123 | 124 | 125 | 126 | 127 | 128 | 129 | 130 | 131 | 132 | 133 | 134 | 135 | 136 | 137 | 138 | 139 | 140 | 141 | 142 | 143 | 144 | -------------------------------------------------------------------------------- /ecosystem/demoapp/scene2.xml: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 28 | 29 | -------------------------------------------------------------------------------- /ecosystem/demoapp/src/agent.cpp: -------------------------------------------------------------------------------- 1 | // 2 | // pedsim - A microscopic pedestrian simulation system. 3 | // Copyright (c) 2003 - 2012 by Christian Gloor 4 | // 5 | 6 | 7 | #include "agent.h" 8 | #include "obstacle.h" 9 | #include "config.h" 10 | #include "scene.h" 11 | 12 | #include 13 | #include 14 | #include 15 | 16 | extern Config config;

It is 5 | suitable for use in crowd simulations (e.g. indoor evacuation 6 | simulation, large scale outdoor simulations), where one is interested 7 | in output like pedestrian density or evacuation time. Also, the 8 | quality of the individual agent's trajectory is high enough for 9 | creating massive pedestrian crowd animations (e.g. for motion pictures 10 | or architectural visualization). Since libpedsim is easy to use and 11 | extend, it is a good starting point for science projects. See the 12 | [examples](http://pedsim.silmaril.org/examples/) page for example 13 | pictures, short movies, and for screenshots. 14 | 15 | The PEDSIM library allows you to use pedestrian dynamics in your own 16 | software. Based on pure C++ without additional packages, it runs 17 | virtually on every operating system. PEDSIM has been developed and 18 | tested on [Linux](@ref linux). Also supported, but slightly less 19 | tested, is [Visual Studio](@ref windows) on Windows. In the 20 | [ecosystem](http://pedsim.silmaril.org/ecosystem/) directory you find 21 | additional parts that use or extend the PEDSIM library. They are meant 22 | to give a quick overview of the capabilities, and are starting points 23 | for your own experiments. Most of them are built using the Qt 24 | Framework, which you'll need to download separately. 25 | 26 | The pedestrians are visible on the user interface in real-time. Using 27 | the file or network-based output, both batch and real-time processing is 28 | possible. 29 | 30 | To create video sequences the output of PEDSIM is usually fed into a 31 | rendering engine, where realistically looking humans are 32 | created. These humans walk based on the trajectories generated by 33 | PEDSIM. 34 | 35 | 36 | ## General Usage Notes 37 | 38 | - Create a Ped::Tscene 39 | - Create a Ped::Tobstacle 40 | - Add the Ped::Tobstacle to the scene 41 | - Create a Ped::Tagent 42 | - Create a Ped::Twaypoint 43 | - Add the Ped::Twaypoint to the Ped::Tagent 44 | - Add the Ped::Tagent to the Ped::Tscene 45 | - Call Ped::Tagent->move() for each timestep 46 | 47 | See the Code Example further down, and have a look 48 | at the full source code, available on the download page. 50 | 51 | ## Detailed Class Documentation 52 | 53 | There is a complete documentation of the classes in the library. It is 54 | automatically generated out of the source code. You can 56 | access this documentation online here. This same documentation is 57 | delivered as PDF file with the library for offline use. 58 | 59 | ## Code Example 60 | 61 | This example shows the very basic usage of the library. No fancy 62 | graphics, of course, only text output to the console. This is 63 | example01.cpp in the examples folder. 64 | 65 |
Please note:
Additional steps 66 | around the example code might be required in order to compile it. If 67 | you are using _Windows_ and, for example, _Microsoft Visual Studio_, 68 | you can create a new console application using the wizard. Create a 69 | file called `example01.cpp` and copy-paste the code into it. In the 70 | project's _Properties_, under _Linker/Input_, add `libpedsim.lib` in 71 | front of the _Additional Dependencies_ list. Click run. Also see @ref windows.
72 | 73 | On a typical [linux](@ref linux) system, if you are in the 74 | _libpedsim_ folder, use this to compile, link and run: 75 | 76 | ~~~~ .sh 77 | g++ examples/example01.cpp -o example -lpedsim -L. -I. -std=c++11 78 | export LD_LIBRARY_PATH=. 79 | ./example 80 | ~~~~ 81 | 82 | It will create 100 agents, which are placed somewhat randomly 83 | distributed around -50/0. They should walk between -100/0 and 100/0. 84 | An obstacle (wall) is placed from 0/-50 to 0/50. The agents must walk 85 | around that obstacle. That's it, as simple as that: the agents will 86 | walk with that little code. 87 | 88 | If you want to display some graphics, write a file, or send data over 89 | the network, you will get the agent's positions with 90 | a->getPosition(). Of course, you can inherit your own classes from 91 | Tagent, Tobctacle etc, if you want to have more control. See the Demo 93 | App Source for an example. 94 | 95 | \include examples/example01.cpp 96 | 97 | -------------------------------------------------------------------------------- /libpedsim/documentation/95-setup.md: -------------------------------------------------------------------------------- 1 | Using PEDSIM on Linux {#linux} 2 | ===================== 3 | 4 | These are some notes regardng setting up a Linux development system for PEDSIM. If you have written software before, you might have everything needed in place already. 5 | 6 | Basically you need a C++ compiler to compile _libpedsim_ (the core library of PEDSIM). Graphical bits of the ecosystem folder require _Qt5_ - see here https://www.qt.io/developers/. Other compilers might work - make sure they support *C++11*. 7 | 8 | 9 | ## C++ Compiler 10 | 11 | I personally use _gcc version 5.4.0_ on a _Linux Mint_ system. _gcc 4.8_ probably works just fine. 12 | 13 | ## Preparing a system for software development 14 | 15 | You should be root for these steps: 16 | ~~~~ .sh 17 | sudo -s 18 | ~~~~ 19 | 20 | First install the C++ compiler: 21 | ~~~~ .sh 22 | aptitude install gcc g++ 23 | ~~~~ 24 | 25 | For the graphical bits install _Qt5_: 26 | ~~~~ .sh 27 | aptitude install qt5-default qt5-qmake qt5-style-plugins 28 | ~~~~ 29 | 30 | 31 | If you want to update the PEDSIM documentation, you need _Doxygen_ and, if you want pdf output, _LaTeX_: 32 | ~~~~ .sh 33 | aptitude install doxygen 34 | aptitude install texlive-full 35 | ~~~~ 36 | 37 | 38 | Good luck! 39 | -------------------------------------------------------------------------------- /libpedsim/documentation/96-windows.md: -------------------------------------------------------------------------------- 1 | Using PEDSIM on Windows {#windows} 2 | ======================= 3 | 4 | This document explains how to use [_Microsoft Visual Studio Community 2015_][msvc] and [Qt _5.7_][qt] to compile PEDSIM and the examples. 5 | 6 | [msvc]: https://www.visualstudio.com/vs/community/ "Visual Studio Community" 7 | 8 | [qt]: https://www.qt.io/download/ "Qt Download Page" 9 | 10 | 11 | libpedsim 12 | --------- 13 | 14 | Basically, in _Visual Studio_, create a new project of type _Win32 15 | Console Application_, and click "DLL" in the wizard. Uncheck the 16 | "Precompiled Header" and "Security Development Lifecycle (SDL) checks" 17 | boxes. This will open a new project containing a few empty 18 | documents. Add all `.cpp` Files to the "Source Files" filter, and all 19 | `.h` files to the "Header Files" filter. Then remove the files that 20 | Windows generated for you, they are not used. 21 | 22 | If you click "Build", Visual Studio will generate a `libpedsim.lib` and a `libpedsim.dll` file. 23 | 24 | Such a solution file is located in the "msvc15" folder. If you have 25 | installed Visual Studio, double click `libpedsim.sln`. Then, once the 26 | IDE has opened, use "Build Solution F7" from the menu. This will 27 | generate a folder called "x64" (on a 64bit system), with a subfolder 28 | called "Debug". In there are the compiled library files. Copy 29 | `libpedsim.dll` and `libpedsim.lib` into the `/pedsim/libpedsim/` folder 30 | (where the `.cpp` and `.h` files are). 31 | 32 | 33 | Examples (and your own programs): 34 | --------------------------------- 35 | 36 | Again, create a new _Win32 Console Application_ project. This time, do 37 | not check he "DLL" box (still uncheck the others). I think the default 38 | is "Console Application" here; leave that as it is. Again, remove the 39 | auto-generated files, and add e.g. the file `example03.cpp`. 40 | 41 | Now here comes the tricky part. You have to specify the include and 42 | library directories. Go to "Project Properties Alt+F7". You probably 43 | have to select the item below the top item in the menu at the 44 | left. The first is the "solution", the second is the "project" which 45 | is what we need. Once opened, there is a window with "Configuration 46 | Properties". Go to "VC++ Directories". Add the path to the libpedsim 47 | source files to the "Include Directories". This is where the 48 | `ped_*.cpp`/`.h` files are. Then, do the same with "Library Directories", 49 | where you add the path to the libpedsim.lib file generated while 50 | compiling libpedsim. 51 | 52 | A bit further down should be a tab called "Linker", and "Input". There 53 | you have to add `libpedsim.lib` to the list of libraries to include 54 | ("Additional Dependencies). 55 | 56 | Now you should be able to build the example. Again, one sample project 57 | file is in the examples folder. Theoretically, it should be possible 58 | to open that using _Visual Studio_, and just click on "Build Solution 59 | F7" to compile `example03.exe`. 60 | 61 | Once you have generated the `example03.exe` file, you need to copy the 62 | `libpedsim.dll` file into that folder (next to the `.exe`). This is 63 | because `libpedsim.dll` is not installed in one of the system-wide 64 | folders. 65 | 66 | 67 | 2-dimensional visualizer 2dvis 68 | ------------------------------ 69 | 70 | 2dvis is built on _Qt_. If you want to use all the features (especially 71 | charts), you need _Qt 5.7_ or above. It should be possible to compile it 72 | using an older version. However, you will not see the metrics charts in 73 | 2dvis then. 74 | 75 | Download the latest version of Qt, and install it. I think you only 76 | need the msvc15 files, about 3.0 GB. I assume _Visual Studio_ has been 77 | installed in the steps above. It is possible to use e.g. _Cygwin_, but 78 | that is beyond the scope of that short introduction. 79 | 80 | Once _Qt_ is installed, simply double click the `2dvis.pro` file. This 81 | will open _Qt Creator_ with the project loaded, where you can build 82 | `2dvis.exe`. Before you can start the application, you need to copy various 83 | `Qt` libraries into the same directory. Easiest is to just double click 84 | the `2dvis.exe` file, and see what happens. These `qt5*d.dll` libraries 85 | are somewhere in your _Qt_ installation folder, located (probably) under 86 | `C:\Qt\...\bin`. Once the required ones are there, start 2dvis using the 87 | command line: 88 | 89 | 90 | Run 2dvis from the command line: 91 | ~~~~ .sh 92 | 2dvis.exe -n 2222 93 | ~~~~ 94 | 95 | This starts a 2dvis that is listening on network port 2222 for 96 | incoming data (used by the Ped::UDPOutputWriter class of _libpedsim_ 97 | in the examples). 98 | -------------------------------------------------------------------------------- /libpedsim/documentation/98-contributors.md: -------------------------------------------------------------------------------- 1 | PEDSIM Contributors 2 | =================== 3 | 4 | PEDSIM was written mostly by Christian Gloor.
